Raph, this is not exactly the same problem (you have a different graphic card, see bug title). BTW, latest restricted-manager now uses xorg.conf directly, so you do not need the dpkg-reconfigure dance any more. If you start 'sudo restricted-manager' from a terminal, are there any messages? Please copy&paste them here.
Roberto, harrydb, please upgrade your system to the latest packages/kernel and try again. -- does not offer driver for GeForce 6800 https://launchpad.net/bugs/96832 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
